  3. Lower left corner of HomeKit Accessory Simulator, click "+" and then "New IP Camera" New IP Camera menu item

  4. In the "Configure your new IP Camera" section, fill in a name, manufacturer and model. Make up something interesting. Click "Finish". NewImage

  5. Scroll down in bottom half of window, click "Start". Camera image should appear.

You now have a HomeKit Camera running. See that "Setup code" at the top of the window? To add it on your iPhone...

  2. Touch "+" button

  3. Touch "Add Accessory".

  4. Point camera at the Setup Code in HomeKit Accessory Simulator on your Mac.
